Previously, there was a question: when Ethereum Layer 2 such as OP and ZK are competing to bloom, will the new public chain still have a chance?

Today, BNBCHAIN ​​has given its own answer - the expansion solution opBNB based on OP Stack.

L2 is not exclusive to Ethereum, and new public chains will also join the L2 battle.

What exactly is opBNB? What changes will it bring to the entire market?

What is opBNB?

opBNB is a second-layer network (Layer2) on BSC built based on OP Stack technology. Like Ethereum Optimism Rollup, opBNB calculates and packages transaction data off-chain and submits it to Layer1 uniformly to improve network performance and ultimately achieve high TPS. , low gas costs and security consistent with Layer 1.

Little knowledge points:

Previously, Binance Chain (Binance Chain, BC) and Binance Smart Chain (BSC) merged into one and were renamed "BNB Chain".

BSC is a subset of BNB Chain. opBNB is built on BSC, so it can also be called the L2 of BNB Chain.

What are the characteristics of opBNB?

1. Based on OP Stack: A set of standardized open source modules that can be assembled into a customized chain. For example, Coinbase's Base is also based on OP Stack. The difference is that Base is Ethereum L2, while opBNB is BSC's L2.

Why choose OP instead of the popular ZK?

Op Rollup focuses on practicality, is simple and easy to use, has a high degree of customization, is truly EVM compatible, and can be quickly implemented into application development and user use. ZK has a big narrative, but it cannot be fully implemented now.

2. Fast and accelerated: Compared with Ethereum, BSC can be called "fast", while opBNB is fast and accelerated.

It is reported that opBNB will increase the Gas limit "to an astonishing 100M", exceeding Optimism's 30MGas limit, processing 4000+ transfer transactions per second, and the average cost of each transaction is less than $0.005.

3.BNB greenfield as the DA layer: In order to reduce Gas, opStack separates the DA (data availability) layer from the execution layer, and you can choose the DA layer yourself. opBNB will use its own BNB greenfield as the storage layer.

What is the strategic significance of opBNB?

Theoretically, with opBNB, individual users will get a better on-chain experience: faster speeds, lower fees. Because EVM is compatible, developers can quickly migrate projects on Ethereum or BSC L1. Not only can DeFi take root on it, but applications such as games and social networking will also enjoy the benefits of low cost and high speed.

But from a practical point of view, after all, it is a bear market now. Currently, BSC does not have obvious bottlenecks in terms of TPS or Gas fees. Therefore, in the author’s opinion, opBNB is facing the future, especially when the OP and ZK series are running fast. Naturally, BSC cannot lag behind others. This is preparing for the future L2 war.

One is waiting for the bull market, and the other is waiting for the popularization of large-scale applications, especially those applications that require high performance, low latency, and high interaction frequency. What are the main ones?

The author believes that there are mainly the following categories: games, especially full-chain games; on-chain social networking with real scarcity scenarios; Metaverse that accommodates many real users; high-frequency trading...

Only then can opBNB truly come into its own.

The security cornerstone of L2 is based on L1 and uses L1 Token as Gas. opBNB also uses BNB as Gas and payment method, which will greatly expand the application scenarios of BNB in ​​the future.

In addition, opBNB can also be fully integrated with the BNB ecosystem. This is the biggest advantage of opBNB compared to other L2s. It can directly utilize the huge user base of the BNB ecosystem without having to go from 0 to 1 by itself.

Finally, I hope that opBNB can really show its talents. When the day when the chain is busy really comes, it means that the bull market may not be far away.
